ABSTRACT The variations of thermal conductivity (K) with temperature for Al–xZn (x = 5, 10, 20, 30, 50 and 60 wt. %) alloys were measured by using a radial heat flow furnace. The variations of electrical conductivity (σ) of solid phases with temperature for the studied alloys were determined from the Wiedemann-Franz and Smith-Palmer equations by using the measured values of K from the plots of K. The thermal temperature coefficient (αTTC) and the electrical temperature coefficient (αETC) were obtained. Dependency of the αTTC and αETC on the composition of Zn in the Al−Zn alloys was also investigated. According to the present experimental results, K of Al–Zn alloys linearly decrease with increasing temperatures up to the melting temperature for each composition and exponentially decrease with the increasing Zn content. On the other hand, the σ of Al based Al-Zn alloys exponentially decrease with increasing temperature and Zn content.

热导率和电导率对温度和 Al-Zn 合金中 Zn 成分的依赖性

摘要 Al-xZn (x = 5, 10, 20, 30, 50 和 60 wt. %) 合金的热导率 (K) 随温度的变化是通过使用径向热流炉测量的。所研究合金的固相电导率 (σ) 随温度的变化由 Wiedemann-Franz 和 Smith-Palmer 方程通过使用 K 曲线中的 K 测量值确定。热温度系数 (αTTC) 和获得了电温度系数（αETC）。还研究了 αTTC 和 αETC 对 Al-Zn 合金中 Zn 成分的依赖性。根据目前的实验结果，Al-Zn 合金的 K 随温度升高而线性下降，直至每种成分的熔化温度，并随着 Zn 含量的增加呈指数下降。另一方面，
